Control Flow & Loops

The break statement in JavaScript terminates the loop or switch statement immediately. When encountered, it causes execution to jump out of the current loop (for, while, do...while, or switch) to the statement following the loop or switch. The break statement does not continue with the next iteration (that's what continue does), and it cannot be used to exit a function (for that, you would use return). It's a powerful flow control tool, but should be used judiciously, as excessive use can make code harder to follow.
